Definitions

  • Agricultural field sprayers are used to apply agricultural products onto a field.
  • Field sprayers can be a self-propelled vehicle or towed/hitched to a towing vehicle, such as a tractor.
  • a sprayer can have a wide applicator boom that is typically folded for transport, and on which nozzles for application of the product are distributed along the length of the boom.
  • Applied products are typically liquids that serve to fertilize seed and plants or to combat weeds, diseases, or pests.
  • the applied product is typically intended to be applied in predetermined amounts per unit of area over a field. In order to apply a desired amount effectively the applicator boom is moved over the ground at a predetermined, specified height.
  • the product may be distributed over an area greater than desired, and if it is too low the product may be released in an area smaller than desired.
  • the height and lateral tilt of the applicator boom can be varied and the tilt of the applicator boom may be remotely or manually controlled to guide the boom substantially parallel to the ground at a desired height. When the ground is uneven or when the field sprayer travels around a curve, the height may be compromised due to tilt of the boom, or oscillations of the boom.
  • a suspended center frame attached to boom wings and suspended from a fixed center frame.
  • a suspended center frame can be suspended from a fixed center frame with a bearing coupling to allow for movement (e.g., pivoting) in multiple axes (e.g. pitch, roll, yaw).
  • links can connect either side of a lower portion of the suspended frame to the fixed frame, which can control the type and amount of movement about the shaft, and dampers may control the rate of pivoting.
  • the pivot point can be located above a center of gravity of a suspended portion of the system, and the links and dampers can be used to dampen the yaw, pitch and roll of the suspended frame relative to the fixed frame.
  • a fixed frame can be operably, fixedly engaged to a sprayer vehicle.
  • the fixed frame can comprise one or more controllable springs, and can comprise a fixed coupling that provides a pivot point.
  • a suspended frame can operably couple with a pair of boom wings to form a suspended portion.
  • the suspended frame can comprise a suspended coupling disposed above a center of gravity of the suspended portion.
  • the suspended coupling can provide for pivoting of the suspended frame about the fixed coupling in roll, yaw, and pitch axes.
  • the suspended frame can comprise one or more dampers operably, pivotably coupled with the fixed frame to dampen movement of the suspended frame in the roll axis.
  • the one or more controllable springs can engage with the suspended frame to control a position of the suspended frame with respect to the fixed frame.
  • a suspended boom frame can comprise a pair of boom arms that, in conjunction with the suspended boom frame, form a suspended portion.
  • a suspended coupling can operably, pivotably couple with a fixed coupling on a fixed frame of a boom sprayer, where the suspended coupling is disposed centrally above a center of gravity of the suspended portion.
  • a pair of connecting links can respectively be operably disposed at opposing bottom corners of the suspended boom frame. The respective connecting links can extend forward to operably couple with the fixed frame at opposing sides to control yaw pivot and/or pitch pivot of the suspended frame.
  • a pair of dampers can respectively, operably extend inward toward a central bottom of the fixed frame, and operably couple with the fixed frame to dampen roll pivot of the suspended frame.

  • a pair of dampers can respectively couple between the suspended frame and a central bottom portion of the fixed frame to control roll pivot of the suspended frame.
  • a suspended center frame boom can be devised that is suspended from a fixed center frame.
  • a suspended center frame of a boom-type agricultural sprayer can be suspended from a fixed center frame with a shaft and a spherical bearing to allow for movement (e.g., pivoting) in multiple axes, instead of just a fixed rotation of a typical pendulum.
  • links can connect either side of a lower portion of the suspended frame to the fixed frame, which can control the type and amount of movement about the shaft.
  • the pivot point e.g., shaft and bearing
  • the links can be used to dampen the roll of the suspended frame (e.g., and yaw and pitch), for example, instead of using fixed contact locations used in current systems.

  • the dampers 110 reduce the rate of pivot in the roll axis (e.g., mitigate oscillation).
  • the dampers 110, 110' can be adjusted to adjust the dampening coefficient, for example, to control the rate of pivot to a desired rate.
  • the left 108' and right 108 connection links are skewed, and help reduce the rate of pivot in the yaw direction.
  • the left bumper 160' is in contact with the left bumper stop 404', mitigating roll of the suspended frame past the left bumper stop 404' (e.g., about eight degrees of roll).
  • the center of gravity of the system 100 while coupled with boom wings 1004, 1006 can be disposed behind the fixed frame 150, such as at the pivot point of the shaft 164 and shaft coupling 106.
  • the suspended frame 102 in a neutral position (e.g., on flat ground), the suspended frame 102 may be disposed in substantially central alignment with the fixed frame 150. That is, for example, in the neutral position the suspended frame is not subject to roll, yaw or pitch pivoting.
  • the center of gravity may be disposed forward of the pivot point, resulting in the suspended frame pivoted in a yaw axis (e.g., the bottom may be tilted forward).
  • the frame pitch bumpers 226, 226' may provide a stop (e.g., which may be cushioned) for the suspended frame 102, stopping it from hitting the fixed frame 150.
  • exemplary is used herein to mean serving as an example, instance or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete fashion.
  • the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, "X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then "X employs A or B" is satisfied under any of the foregoing instances.
  • At least one of A and B and/or the like generally means A or B or both A and B.
  • the articles “a” and “an” as used in this application and the appended claims may generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
  • the claimed subject matter may be implemented as a method, apparatus or article of manufacture using standard programming and/or engineering techniques to produce software, firmware, hardware or any combination thereof to control a computer to implement the disclosed subject matter.
  • article of manufacture as used herein is intended to encompass a computer program accessible from any computer-readable device, carrier or media.
